Bioflocculation of Wastewater Treatment Pond Suspended Solids
… of Wastewater Treatment Pond Suspended Solids</strong></p> <p><strong>Louis Lefebvre</strong></p> <p>Wastewater treatment lagoons and high rate algae ponds (HRAPs) can provide cost effective wastewater treatment, but they commonly have high effluent concentrations of total …

Spectral analysis of total suspended solids mixtures for solids composition determination
Total Suspended Solids (TSS) analysis provides an initial and very basic measure for study and characterization of water quality. The present tedious procedures used for the identification of different solids constituents present in TSS and for the classification or insight into the origins of …

Concentration of Suspended Solids and Nutrients in Overland Flow in Suburban Philadelphia Watersheds
… phosphorous (TDP), total phosphorous (TP), suspended sediment concentration (SSC), and chloride (Cl), and results were compared to catchment metrics including area and land cover. OLF samples showed a wider variability of sediment, chloride, and nutrient concentrations than stream samples, …

Evaluation of Nutrients and Suspended Solids Removal by Stormwater Control Measures Using High Flow Media
… over 11 months to assess the removal of Total Suspended Solids (TSS), Nitrogen, and Phosphorus in First Flush (FF) stormwater runoff. Excellent removal of TSS and particulate-bound nutrients was noted, but, in most SCMs, removal of dissolved species was limited. Sorption of dissolved P …

Injection Impairment by Suspended Solids: Well Models, Filtration Parameters, and Models’ Validation with 3-D Injection Experiments
… pressure maintenance and disposal. However, suspended particles in produced water cause formation plugging, resulting in reduced permeability and loss of injectivity. Water injection, without solids suspension, at high velocity generates a loss of injectivity as a non-Darcy flow effect. The …

The capacity of native fish and a freshwater mussel species to control suspended solids in wastewater stabilization ponds
… to control phytoplankton biomass and reduce suspended solids can provide small, rural communities with inexpensive, secondary wastewater treatment. The capability of several native fish species and the freshwater mussel, <i>Elliptio complanata</i>, to reduce suspended solids and phytoplankton …

Application of Ozone in Dissolved Air Flotation (DAF) for Enhanced Removal of TOC and Suspended Solids in Pulp and Paper Wastewaters
Pulp and paper mills are one of the top consumers of water related to industrial manufacturing, which ultimately leads to a large volume of heavily contaminated wastewater. This discharged effluent can have a harmful effect on the receiving aquatic environment and cause further ramifications …

Agricultural and forest land runoff in upper South River near Waynesboro, Virginia
Sources and yields of organic matter, suspended solids and nutrients in the Upper South River Basin were investigated during the summer low flow period of 1974. Parameters monitored at sampling stations in the basin included chemical oxygen demand, total suspended solids, turbidity, specific …

Aerobic digestion of waste activated sludge from biological nutrient removal activated sludge systems
… biodegradable and non-biodegradable volatile suspended solids (VSS) and non-volatile inorgainic suspended solids (ISS). Stabilization for safe disposal of the WAS is a process of paramount importance at wastewater treatment plants (WWTPs). Hence, aerobic digestion of the WAS from biological …

Characterization and treatment of spent vegetable tan liquors
… because it effectively reduced the color and suspended solids of the tanning waste. Aeration was thought to be a possible means of reducing the Chemical Oxygen Demand of the waste by biological stripping of the pyrogallol compound in the spent waste. Samples collected from the …

A methodology for the design of wet detention basins for treatment of highway stormwater runoff
… determine the settling velocity distributions of suspended solids to refine a methodology selected by the FHWA in designing wet detention basins for the treatment of highway stormwater runoff. Thirteen runoff samples were collected, over two years, from high volume (greater than 100,000 vehicles …

Effects of holding tank odor control chemicals on aerobic wastewater treatment
… flow bioreactors were monitored for changes in suspended solids, specific oxygen uptake rate, sludge settling and compaction, and effluent COD. The biodegradability of dyes and the generation of foam was also measured. Formaldehyde and the formaldehyde-based odor control chemical "Aqua-Kem" …

Testing the use of the BASINS PLOAD model to simulate the quality of stormwater runoff from the Kuils River catchment, Cape Town
… freshwater resources. Total phosphorus and total suspended solids represent two forms of pollutants that are commonly found in non point source discharge...This study evaluated water quality modelling as an alternative monitoring technique. The study was aimed at determining the potential use of a …

Ozone treatment of a selected textile dyeing and finishing wastewater
… total organic carbon, ozone residual, total and suspended solids, and turbidity. The results of the investigation showed that color was removed to a significant degree from the selected wastewater by the action of ozone. Up to 80 percent of the original color of the wastewater was removed by …

Investigation of Dairy Wastewater Using Biowish
… degradation of biochemical oxygen demand (BOD), solids, and nitrate concentrations. The dairy wastewater was augmented with various bacterial composition obtained from BiOWiSH<sup>TM</sup>. The bacterial mixes experimented were US Aqua, Thai Aqua, BMT, Osprey, Fruit Wash, KLB, LCM1, and MDG. …

Evaluation of Sedimentation Control as a Best Management Practice for Removing Copper-based Crop Protectants in Plasticulture Runoff
… the runoff with the majority, 74%, sorbed to the suspended solids. The remaining copper, 18%, leached through the soil and entered the groundwater with 10% in the dissolved phase and 8% sorbed to suspended solids. Although only one-percent of the copper was found to leave the field, this was …
